Dorchester District 2 voted unanimously Wednesday to seek a referendum of up to $177 million on the November ballot to build new schools and renovate others.

Each school in the district will see some benefit if the referendum passes. Projects range from new roofs to heating and air-conditioning systems to new classroom wings. It also included several new schools to ease overcrowding.

In addition, the board voted to allow the public to vote on three separate options: an auditorium, an aquatics center and libraries. Each would be adjacent to schools and accessible to the public.
